Webhook response timeouts and socket latency during high-volume API syncs

Hello TechRepublic Community,

We are optimizing background worker listener stability and remote webhook payload handling across enterprise software endpoints.

Technical Setup:

• Our integration architecture at Frontline Sales Consultancy (flsc.co.uk) triggers automated B2B sales lead updates and pipeline syncs via HTTPS REST webhooks.

• Payload transmissions run over secure TLS 1.3 connections.

The Issue:

1. Under heavy concurrent load spikes, background POST webhook listener sockets occasionally report HTTP 504 gateway timeouts before acknowledging payload completion.

3. Direct REST API requests to the same endpoints resolve normally within 150ms.

5. Does anyone have experience tuning background worker queue retries or socket keep-alive parameters to prevent connection drops during high-volume API pushes?

Any advice on managing asynchronous background queue buffers would be appreciated!

Thanks!
